which is obvious and needs no further description.

The outside casing is made of two sections designated by the numerals 39 and 4l, the latter part having a filler ring 41A. The section 39 is riveted to an angular member 37, which is rotatable on the cap 31, as shown at 42. IVhile the portion 4l is screwed to the angular member 19 by the screws 2l, a split ring vis secured to the interior of the portion 39 by rivets 43. This split ring is pivoted with a groove 46 which engages the rivets 45 in such a manner as to have sliding contact therewith. This casing is preferably made of material which will not conduct heat.

Openings are formed therein as shown at 44, which openings permit the escape of excess pressure within the barrel 24. This escape is permitted by the introduction of a safety valve 46, which is secured to a barrel 24 as by a spring lever 47 and a screwv48.

.The manner of operating my torch is as follows It is first necessary to remove the filler plug 38 and introduce a liquid fuel 'such as gasoline or the like into the reservoir formed by the extremity 14, the cap 3l and the barrel 24. When a suflicient quantity of fluid has been placed therein the cap 38 is replaced, the torch is then held in vertical position with the tipA upward. The gasoline is then placed within the cup bottom 22 andi ignited. y The burning of this gasoline heats the neck 5, the head 6 and tip 7. When the same has reached a sufficient Vtemperature to cause gasificationr of the liquid passing through the neck, the handle is grasped,

the portion 41Vin vone hand and the portion 39 in the other hand. Y

By now holding one of these and rotating the other the fact4 will be that the annular member 37 with its slot 36 will cause the handle 34 of the needle valve to be rotated. This will in turn, through the threaded portion 33, open the needle valve and permit gaseous fuel to escape from the reservoir through the wick channel 27, 26 bore 13 to the burner tip l2 where it will become ignited, theproducts of combustion passing out through holes 8 and 9 and at the same time heating the tip 7;. Should the pressure within'he reservoir become excessive, the safety valve 46 Vwill openrpermitting the pressure to drop to Zero whichwill extinguish the ame in the head while the gas will escape through the openings 44.

It will thus be seen that I have produced p .Y an iron which will accomplish all the objects above set forth. f It is to be understood that the form o said ring and said cap, said casing being formed by two parts, one of said parts be'- ingrsecured to said ring, the other of said parts being rotatably supported on said ,cap and a needle valve extending through said cap and adapted to closevsaid bore in said neck, and means carried by said casing for rotating said needle valve.V

2. In a tocllof the character described a reservoir having a neck portion provided with a bore therethrough, a burner tip carried by said neck portion, a head surrounding said burner tip and secured to said neck, a soldering tip secured to said head,

a ring secured to said neck, a cap secured .Y

to said reservoir at the opposite end thereof from said ring, a casing extending between saidV ring and said cap, said casing being formed by two parts, one of said parts being secured to said ring, the other of said parts being rotatably supported on said cap and a needle valve extending through said cap and adapted to close said bore -insaid neck, means carried by said casing for rotating said needle valve, said casing ybeing spaced from said reservoir, a safety valve secured to Vsaid reservoir and positioned in the space betweenV ysaid reservoir yand said casing, and ports formed in said casing to permit the'escape of excess pressure created in said reservoir.
